The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
It's almost JSON you could parse:
ReplyDeleteJSON.parse('{key1=value1, key2=value2}'.replace(/=/g,":"))
EDIT With keys as strings (thx @MattGreer):
JSON.parse('{key1=value1, key2=value2}'.replace(/(\w+)=/g, '"$1":'))
EDIT With values as strings (thx @ajsie):
JSON.parse('{key1=value1, key2=value2}'.replace(/(\w+)=(\w+)/g, '"$1":"$2"'))
This could work. Not tested though.
ReplyDeletevar data = '{key1=value1, key2=value2}',
values = data.match(/\w+=\w+/g),
newObject = {},
i, value;
for (i=0; i < values.length; i++) {
value = values[i].split('=');
newObject[value[0]] = value[1] ;
};
In that format nothing built in will help you. That's not quite a valid object literal, so eval will fail (eval should be avoided anyway), and it's not quite a JSON string, so JSON.parse will fail too. Can you massage the format? If you could get it to be {"key1": value1, "key2": value2 }, then both of the things I mentioned would work out of the box. JSON.parse in particular would be good:
ReplyDeletevar resultingObject = JSON.parse('{"key1": value1, "key2": value2 }')
It will (probably) be easier to massage the data into a valid JSON format than try and write your own parser. But if you have no choice on the format, a parser is probably your only option.
In desperation, a crude function to convert the format to JSON through brute force (replace all '=' with ':', wrap the keys in quotes, probably via a regex) would work, but it'd be brittle.
If the values are numbers, not strings, and the info came from a trusted source, then you could simply eval the string.
ReplyDeleteIf the values can contain strings then you'll need to parse it.
Added: oops, I forgot that the key/value separator is a colon, not an equals. @sinsedrix solution is good, except that you need to eval it since it still isn't valid JSON. (JSON requires that the keys be strings, not bare-words.)
